kierownika
The Polish word "kierownika" means "manager" or "supervisor" (genitive or accusative form).
The word 'kierownika' here is in the accusative case, indicating it as the direct object of the verb 'Spotkałem' (I met).
Spotkałem kierownika tego działu w biurze.
I met the manager of this department in the office.
Here, 'kierownika' is in the genitive case again, denoting possession as it refers to 'propozycje kierownika' (manager's proposals).
Podczas rady omawialiśmy propozycje kierownika.
During the council, we discussed the manager's proposals.
In this sentence, 'kierownika' is in the genitive case, indicating possession as it modifies the noun phrase 'dla kierownika projektu' (for the manager of the project).
